Electrical connector with crosstalk compensation

Abstract

An electrical connector with crosstalk compensation includes a substrate ( 10 ), a first conducting group (G 1 ), a second conducting group (G 2 ), a first metal conducting wire (C 1 ), and a second metal conducting wire (C 2 ). A first conducting pair (S 21 ) of the second conducting group (G 2 ) is electrically connected to a first conducting pair (S 11 ) of the first conducting group (G 1 ) to form a first signal loop pair (L 1 ). Furthermore, a second conducting pair (S 22 ) of the second conducting group (G 2 ) is electrically connected to a second conducting pair (S 12 ) of the first conducting group (G 1 ) to form a second signal loop pair (L 2 ). The first metal conducting wire (C 1 ) and the second metal conducting wire (C 2 ) are electrically connected to a second conductor (R 21 ) and a fourth conductor (R 22 ) of the second conducting group (G 2 ), respectively. Therefore, the first metal conducting wire (C 1 ) and the second metal conducting wire (C 2 ) are installed in parallel on the substrate ( 10 ) to obtain a compensation capacitance to reduce and even cancel a crosstalk noise induced between the first signal loop pair (L 1 ) and the second signal loop pair (L 2 ) when signals are sent through either of the two signal loop pairs (L 1 , L 2 ).
